Barcelona Reset: Circuit of Ephemeral Architecture

During the summer of 2014, new life was injected into the auspicious squares and parks of the city centre of historic Barcelona by the Enric Miralles Foundation. This came in the form of celebrative temporary installations commissioned from teams, including among them Odile Decq, Yael Reisner and Peter Cook, Grafton Architects and Urban-Think Tank. Commemorating the 300th anniversary of the end of the siege of Barcelona, each group of collaborators was asked by the curators, architect Benedetta Tagliabue and theatre director Àlex Ollé, to create a structure that embodied a universal principle, such as diversity, democracy and identity. Benedetta Tagliabue describes the project.     

三维油气成藏动力学建模与软件开发

根据系统工程学的理论与方法,油气成藏动力学模拟的系统工程模型构建思路可概括为:将动力学模拟与非动力学模拟结合起来,用非动力学模拟再造油气生排运聚散过程的物质空间;将常规动力学模拟与系统动力学模拟结合起来,用系统动力学模拟描述系统整体的非线性过程;将数值模拟与人工智能模拟结合起来,用人工智能模拟解决油气运聚等局部过程的非线性问题。需要解决的关键技术包括:三维数字地质体的空间插值与矢量剪切技术,盆地构造史、沉降史的三维回剥与平衡技术,盆地构造应力场的动态模拟技术,多热源多阶段叠加变质作用模拟技术,真三维的常规油气生成、排放动力学模拟技术,油气运移和聚集的人工智能模拟技术,油气成藏的系统动力学模拟技术,以及系统动态连接与集成化技术。作者探讨这些理论难题并取得关键技术上的一系列突破,初步建立了一个三维油气成藏动力学模拟评价系统,并成功地用于实践中去。
